Can we do samashrayanam and bharanyasam under different preceptors? If so whom should we consider our Acarya? Whose custom should be followed during festival times?

If samashrayanam and bharanyasam are performed under different Acarya-s, both have to be revered. If it happens to a woman, once she gets married, she has to follow the custom practiced by her in-laws. For example, if a woman has performed bharanyasam before her marriage, when she gets married into a family of different sampradayam and performs samashrayanam under the Acarya for that family she has to follow the customs and celebrate festivities belonging to that sampradayam.
